Sierra Entertainment is a software label which publishes games from indie developers. Founded in 1980 by Ken and Roberta Williams, it developed and published a large variety of video games, including a number of best-selling games and series, for various platforms between 1980 and 2008. After 1999, Sierra has developed no new games but worked strictly as a publisher. In 2014, the brand was resurrected as an indie publisher by owners Activision Blizzard.
This section is about the series of games more so than the individual title. Individual games are also listed by their year of release.
